OEM Payne 2-Pole Contactor 24V Coil HN51KB024 for Model PA10JA030000ABAA

This is the factory OEM replacement contactor for the Payne PA10JA030000ABAA split-system air conditioner. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and switches line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms include the outdoor unit not powering on at all, the system not responding to thermostat calls for cooling, or visible pitting and burning on the contact points causing intermittent operation or a stuck-closed condition that runs the unit continuously.

  • Specs: 2-pole configuration | 24V coil voltage | OEM part number HN51KB024 | Factory-matched contact rating for Payne PA10JA030000ABAA condensers
  • OEM vs Generic: This OEM contactor is manufactured to exact Payne/Carrier factory specifications. Generic contactors often use lower-grade contact materials that pit and corrode faster, leading to premature failure and potential compressor damage from voltage drop.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker panel before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire connections before removal to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Payne model PA10JA030000ABAA. Always verify coil voltage and pole configuration on your unit's data plate or existing contactor before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — same-day shipping available on all in-stock orders placed before 3 PM.

Frequently Asked Questions

Does this Contactor fit my Payne PA10JA030000ABAA?
Yes. This is the factory-specified OEM contactor for the Payne PA10JA030000ABAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Payne PA10JA030000ABAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Payne parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Payne contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
